Detachable depth-gauge leveling wheel with stubble sweeper

Abstract

A groove depth-leveling wheel used in planting groups defines the depth of the furrow opened by the planting disc for uniform planting. The wheel has blades on its outer side to prevent reeds, stubble, straws etc. from sticking between this wheel and the planting disc and blocking the wheel or the planting disc itself.

The invention claimed is: 
     
       1. A detachable depth gauge leveling wheel with stubble sweeper applicable in planting units mounted to a structure of an agricultural seeder machine and used to define a depth of the furrow opened by a planting disc to achieve uniform planting, with one or two wheels per unit, the detachable depth gauge leveling wheel with stubble sweeper comprising:
 a rim with multiple curved blades projecting from one of its sides towards the outer vertical plane of the wheel and extending between the center of the wheel and a periphery of the wheel and spaced equidistant from each other, leaving multiple curved, open and equal spaces and linked through multiple screws or bolts to a quick-change ring, the quick-change ring linking the rim with a tire and eyelets of the tire and different lateral profiles, since on one side the tire is resting on the rim and, on the other, the tire is related to a quick-change ring, the quick-change ring having a bushing that relates the wheel to a shaft of a mounting arm, with a plurality of lubrication channels on an inner side of the bushing while on its an outer side it has a slightly conical shape, which can be rotated 90° counterclockwise, comprising wedges or ramps on an end of the bushing that interact with similar wedges or ramps on the rim and, at the other end, the bushing has four grooves that can be related to four upper ribs engraved on a cap, which, in turn, has a plurality of lateral ribs and one of the ribs of the plurality of the ribs is linked to a bolt mounted in a housing. 
 
     
     
       2. The detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein the rim is selected from the group of aluminum, steel, gray cast iron, nodular cast iron, plastic, an alloy thereof, or combinations thereof. 
     
     
       3. The detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein screws or bolts are inserted in the eyelets of the tire and in nuts mounted in the corresponding nut-lock housing of the rim. 
     
     
       4. The detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein the cap can be removed after unscrewing the bolt mounted in the housing. 
     
     
       5. The detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein the bushing can be rotated 90° counterclockwise by inserting the upper ribs of the cap into the grooves of the bushing. 
     
     
       6. he detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein the wedges or ramps axially extracts the bushing from inside the rim. 
     
     
       7. The detachable depth gauge leveling wheel with stubble sweeper according to  claim 1 , wherein the bushing and the housing in the rim are threaded and are linked.
